ABSTRACT Diseases caused by SARS-CoV-2 and Mycobacterium tuberculosis ( M.tb ) represent two public health emergencies. In severe disease, both pathogens may share a biological niche in the lower respiratory tract. There is significant potential for infections to be co-present within individuals enhance or moderate respective outcomes of either infection. Here, we investigated how whole blood samples, as well CD4+ CD8+ T cells, from hospitalised with acute COVID-19 disease respond mycobacterial challenge. To do this, samples were assessed ex vivo growth inhibition assays, immune cell phenotyping mass cytometry, cytokine responses antigens flow cytometry. These studies identified subgroup patients whose had an enhanced capacity inhibit growth. The ability control was associated presence non -specific CD28+ population, particular activation status migratory phenotype. This work improves our understanding factors involved control, contribute design novel therapies TB.

This case report aims to elucidate the unique clinical course of a 34-year-old male patient diagnosed with human immunodeficiency virus (HIV), chronic hepatitis C, and prior tuberculosis (TB) infections, who subsequently contracted COVID-19. Immunological assessments revealed profound immunosuppression, marked by decreased CD4+ T cells (0.037 x 10⁹/L), alongside mildly elevated IgG levels (16.701 g/L), reflecting both HIV-related non-adherence antiretroviral therapy (ART). Concurrently, tested positive for SARS-CoV-2. Imaging findings demonstrated overlapping characteristics TB Timely initiation specific therapy, supportive care optimized anti-TB regimens, was implemented. Despite patient's immunocompromised state complex medical history, he successfully recovered from Key factors contributing survival included early diagnosis treatment, comprehensive care, careful management drug interactions, potentially effective individual immune response. Notably, no typical features COVID-19 pneumonia were observed, suggesting that dual infection may have influenced presentation. underscores potential outcomes in individuals histories, including coexisting infections. Further research into interplay multiple infections such patients is warranted optimize strategies enhance our understanding within this distinctive population.
